I just gave the new patch a shot and I'm still experiencing a problem
I've been seeing for some time. I get a segmentation fault in
isight_load_firmware but for what reason I'm unsure. I'm attaching the
dump I find in dmesg. I'd much appreciate any help anyone can give me.
Firmware is where it should be. I've tried with both the version from my
OSX drive and the version in the all-in-one bundle with the same results.
